CPU PnP Setup Page
This page lets you manually configure the mainboard for the CPU.
The system will automatically detect the kind of CPU that you
have installed and make the appropriate adjustments to the items
on this page.
Note
: If you manually set the wrong speed and the system won’t
run properly, press the
Page Up
key while the system is booting
and a default setting will replace the incorrect CPU setting.
CPU Speed
The item displays the internal clock speed of
the CPU, based on the next two items.
CPU/SDRAM
Frequency
Use this item to sets the external clock
frequency for the CPU and the memory bus
frequency. The options include combinations of
66 and 100MHz. Set the CPU clock based on
the requirements of the CPU installed on the
board. Select the memory frequency based on
the speed of the memory installed on the board.
CPU Multiple Freq.
Use this item to set a multiplier for the CPU
external frequency. The multiplier times the
external CPU frequency sets the internal clock
speed of the CPU, e.g. 100 MHz (external clock
or “FSB”) x 4.5 (muliplier) = 450 MHz (internal
clock speed of the installed CPU).
